drivers/misc: make arm-charlcd.c explicitly non-modular
The Kconfig currently controlling compilation of this code is: drivers/misc/Kconfig:config ARM_CHARLCD drivers/misc/Kconfig: bool "ARM Ltd. Character LCD Driver" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. We explicitly disallow a driver unbind, since that doesn't have a sensible use case anyway, and this driver did not have a ".remove" function coded for non-modular drivers either. Since module_platform_driver() uses the same init level priority as builtin_platform_driver() the init ordering remains unchanged with this commit. We don't replace module.h with init.h since the file already has that. We also delete the MODULE_LICENSE tag etc. since all that information is already contained at the top of the file in the comments.
